Hello, I am writing a software which reads xfs partitions and it is working well so far, but, at in a particular folder with 10k files, only 7k files appear, the other ones don't. I read an inode which has di_core.di_format = XFS_DINODE_FMT_BTREE No problem here, the btree is trivial, it has only 1 element inside it, which leads to a list of 82 extends. Extends 0..52 aprox. are all great, and work fine. Extent 53 (and other ones after that) point to very wierd memory areas which don't match the pattern that I saw previously =( Here is the hex data of the extents, the selected extent in nr 53: http://magnifier.sourceforge.net/temp/xfs/extent_with_xfs_bmbt_rec_64.png And here is debug information showing which values I extracted from this table: i=0 FLocalExtent.StartOff=0 FLocalExtent.StartBlock=66748 FLocalExtent.BlockCount=1 lStartBlock=65212 i=1 FLocalExtent.StartOff=1 FLocalExtent.StartBlock=66758 FLocalExtent.BlockCount=2 lStartBlock=65222 i=2 FLocalExtent.StartOff=3 FLocalExtent.StartBlock=66772 FLocalExtent.BlockCount=1 lStartBlock=65236 .... i=51 FLocalExtent.StartOff=77 FLocalExtent.StartBlock=67468 FLocalExtent.BlockCount=1 lStartBlock=65932 i=52 FLocalExtent.StartOff=78 FLocalExtent.StartBlock=67479 FLocalExtent.BlockCount=1 lStartBlock=65943 i=53 FLocalExtent.StartOff=8388608 FLocalExtent.StartBlock=66749 FLocalExtent.BlockCount=1 lStartBlock=65213 i=54 FLocalExtent.StartOff=8388609 FLocalExtent.StartBlock=66783 FLocalExtent.BlockCount=2 lStartBlock=65247 ... Note how StartOff is suddenly so big! But I manually checked the bits comparing to xfs_bmbt_rec_64 and the value written is that one. But what sense does it make for StartOff to jump like that? And why are the blocks pointing to a non-XD2D block? Here is the block to which one of the valid extents point to: http://magnifier.sourceforge.net/temp/xfs/correct_block_xd2d.png And here is a block to which one of the extents that I cannot interpretate point to: http://magnifier.sourceforge.net/temp/xfs/wierd_block_xd2d.png and another one: http://magnifier.sourceforge.net/temp/xfs/wierd_xfs_dir2_data_entry.png Any ideas??? I already worked so much on this, but I cannot figure out =( thanks, -- Felipe Monteiro de Carvalho _______________________________________________ xfs mailing list xfs@xxxxxxxxxxx http://oss.sgi.com/mailman/listinfo/xfs
